Abstract: A method, system and apparatus for allowing a single network adapter to be used by a plurality of partitions of a logically partitioned computer system (LPAR) are provided. Each partition assigns a different IP address to the network adapater. The different IP addresses are stored in a table. The table cross-references each IP address with its partition. When a piece of data is received by the computer system, the data is examined to find out the IP address associated with the data. Once done, the table is consulted to determine to which one of the plurality of partitions the data is to be forwarded. The data is then forwarded to the partition.

Abstract: A data processing network and system in which a network connection is enabled to migrate among a multitude of available servers and/or clients to provide the connection using the most efficient available set of resources. Typically a server and client would indicate their respective support of this connection migration feature when the connection is established. An operating system or application program would monitor existing connections for characteristics including basic functionality and performance. If an existing connection were found to be faulty or low performing and the client and sever associated with the connection supported connection migration, the software would then determine if an alternative and more effective connection existed. Upon discovering such a connection, the parameters that define the connection would be altered to migrate the connection to the preferred hardware. In an embodiment in which the network connections are established with a transmission control protocol (TCP), each connection includes a four-tuple that completely defines the connection, namely, a source IP address, a source port number, a destination IP address, and a destination port number. By altering one or more of the connection's defining four-tuple, the invention is configured to migrate the connection to a NIC or system that is functioning more efficiently.
